聚合铝与有机高分子复合絮凝剂的絮凝性能及其吸附特性

The Coagulating Behaviors and Adsorption Properties of Polyaluminum-Organic Polymer Composites

为探讨聚合铝与有机高分子在复合絮凝作用过程中的相互作用，选取４种典型有机高分子絮凝剂，研究聚合铝与阳离子型有机高分子和阴离子型有机高分子复合后的凝聚絮凝特征及其吸附特性．结果表明，聚合铝与阳离子型有机高分子复合能够使其絮凝效能相互促进，而聚合铝与阴离子型有机高分子的复合只有在药剂投加量达到一定值时才能对絮凝效能起促进作用．阳离子型有机高分子引入聚合铝后，使聚合铝的吸附量降低，而阴离子型有机高分子的引入使聚合铝的吸附能力大大增强。

Several types of polyaluminum organic polymer composite flocculants were prepared and their flocculating behaviors and adsorption properties were also studied.The results showed that flocculating behaviors of polyaluminum chloride (PAC) or cationic organic polymers can be greatly improved by the composition with each other;the flocculating behaviors of PAC can be improved by anionic organic polymers only when the dosage of PAC amouts to a certain value.The adsorption capacity of PAC can be decreased due to the composition with cationic organic polymers,on the contrary,it can be highly increased through the composition with anionic organic polymers.
